Cat#:RP-2801H;Product Name:Recombinant Human Cys-Protein-G;Synonym:Cys-Protein-G;Description:Cys-Protein G Recombinant produced in E.coli is a 196 amino acids protein which contains amino acid 190-384 of the Streptococcus sp and a Cysteine residue at the N-terminus, has a predicted molecular mass of approximately 22.5kDa. But it migrates with an apparent molecular mass of 32kDa in SDS-PAGE. The Protein G is purified by proprietary chromatographic techniques.;Source:E.coli;Purity:Greater than 95.0% as determined by SDS-PAGE and HPLC analyses.;Bioactivity:Please contact us for detailed information;Formulation:Lyophilized without any additives.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized Protein G in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized Protein G although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Protein G should be stored at 4°C between 2-7 days and for future use below -18°C. Please prevent freeze-thaw cycles.;
